Thank you for your reply. I had simulated these examples and has known that the first one had no start value, thus not calulated a solution. I'm trying to find out some error equation like that. Thank you very much.

Hi,
I'm using the OMShell with scripts for simulate, but having an error as followed:
messages = "warning | Error solving nonlinear system SES_ALGORITHM 0 at time 43.3615
infor | model terminate | simulation terminated at time 43.2238
I don't know why had this error
